Zivame — Refund money instead of zcoins

I ordered product worth 5000 rs and when the products were delivered it's too small for me and I returned them and they refunded me zcoins but I want my money back in my account. Only problem is that there size chart is incorrect. That's why I don't wanna shop from zivame in future. I don't want zcoins I want my money. If there's no policy of refunding money then it means there no such policy like returning. Zcoins mean exchanging products within some time period. And that is fraud if I would have known that I will be refunded with zcoins and not money then I would never shop from zivame. Kindly requesting you to refund my money back otherwise I will have to do something about this .
